Ombudsman, also referred to as Ombudspersons and/or Ombuds Institutions, can perform highly segmented monitoring, oversight, arbitration, and investigation roles in military institutions, law enforcement institutions and in the intelligence sector. In some nations, an Inspector General within a security sector agency can perform a similar function. Overall, any nation with an ombuds institution focused on human rights issues will face the challenge of monitoring the security sector and its agencies in one form or another.
